Generalized Total Least Squares with mixed and/or weighted disturbances

The total least squares problem, also known as errors in variables, solves the over-determined set of linear equations (A0+dA)X = (B0+dB), where covariance matrix of the unknown disturbances dA and dB is considered to be diagonal and denoted by E([dA dB]^T[dA dB]) = sigma_d.*I.

The mixed total least squares problem solves the over-determined set of linear equations [A1 A2]X = B, where A1 are the error-free variables, and A2 = A0 + dA2 and B = B0 + dB are the variables with disturbances.
